Solar Lithium Batteries - An Introduction

There are many options for batteries, including electric cars, cell phones, and laptops. This trend will not change in the near future. Global electricity usage is increasing rapidly and smart phones, tablets, and e-readers all become more common. Additionally, as the renewable energy industry grows, batteries are increasingly being used for energy storage. Although many technologies have been developed by engineers and scientists to provide storage, none seem to be the most effective. While flywheel, compression air, thermal storage and grid-scale storage are strong contenders, lithium-ion batteries, nickel-cadmium, and nickel-metal hydride batteries all compete for portable storage. It all boils down to the fact that we still don't know how to store our electricity in an optimal manner. This article will cover the potential and technology behind lithium batteries.

There are many applications for lithium-ion cells, such as electric cars, pacemakers and laptops. They are low-maintenance and very energy dense. There are some drawbacks to commercial lithium-ion cells. They are fragile, expensive, and have a limited lifespan in deep-cycle use. Improvements in cell performance are key to the future of many budding technologies including electric vehicles.

Technology

A battery can be described as an electrochemical device. It is an electrochemical device that converts chemical energy into electric energy. Rechargeable battery can also convert in the reverse direction as they use reversible reacts. A cell's positive and negative electrodes are called the cathode, an anode, and an anode. The electrodes can be placed in an electrolyte, and connected through an external circuit to allow electron flow.

The first home lithium battery were high-temperature cells that contained molten sulfur and lithium cathodes. These thermal rechargeable battery were first made commercially available in 1980. They operate at temperatures of around 400 degrees celcius. Electrode containment proved to be a major problem because lithium's instability. Molten lithium-sulfur cell adoption was slowened by corrosion and better ambient temperature batteries. This is still theoretically a powerful battery but scientists realized that stabilizing energy density was better than sacrificing power. This was the beginning of lithium-ion tech.

A lithium-ion battery usually has a graphitic anode that hosts Li+ and a cathode that houses metal oxide. The electrolyte is made up of a lithium sodium (LiPF6, LBF4, and LiClO4), which has been dispersed in an organic solvent such ether. Because lithium reacts violently with water vapour, the cell is sealed. The electrodes are also separated using porous materials to prevent physical contact. While the cell is charging lithium ions interact with carbon molecules in its anode. At the anode, electrons and lithium ions are also released. During discharge, lithium ions are released from the anode and travel towards the cathode. Because the cell contains the flow of electrons as well as ions, it is essential that the system be both an excellent electrical conductor and an ionic one. The first Li+-based battery was developed by Sony in 1990. It featured a lithium cobaltoxide cathode with a carbon anode.

The many advantages of lithium ion batteries have made them the preferred choice for many applications. Lithium, the metal with the highest electrochemical potential and the lowest molecular mass, is also the best. This is why Li-ion battery can be very dense in energy. Lithium cobaltoxide-carbon is the most common potential for a lithium battery. It has a typical potential of 3.6V. These cells have a lower self discharge rate of 5% than NiCad, which typically self discharge at 20%. They don't contain hazardous heavy metals, such as lead and cadmium. Li+ batteries don't have memory effects, so they do not need to be recharged. Li+ batteries are much more maintenance-friendly than other batteries.

Implementation

While new lithium battery chemistries and products are being developed, Li+ batteries remain at the top of the food chain. Because of its energy density, this technology is often the best choice for electric vehicles or electronic devices. Tesla Roadster has a total of 6831 lithium ion battery packs. These cells, which are arranged in packs of 69, can take the car from 0-60 mph within 3.9 seconds. If you're curious, 69 converts to 6831 exactly 99x. A lithium cell is most likely to power your laptop if it's reading this article.

In the near future, it appears that lithium ion technology will continue dominating many applications. Li+ batteries are a well-proven concept that is unlike other technologies that have remained in the laboratory. Positive effects will undoubtedly be experienced by the industry as a result of the potential emergence electric vehicles and the growing demand for electronics. Unfortunately, not all good things are permanent. Analysts believe that the technology's competitive edge will be lost once the newer technologies, such as zinc-bromine, aluminium-ion, and lead-carbon, are introduced. Lux Research provided the following information on lithium ion batteries for storage applications:

"Liion batteries designed for transportation applications can be considered energy dense storage devices. This is why stationary storage projects don't value it as much, and grid-tied Li-ion batteries systems are often discarded. The grid storage market will be overtaken by rapidly changing technologies with comparable or superior performance metrics, substantially lower costs, and greater resource availability in the future.

Even though they won't be used for large-scale grid storage, Li-ion battery will continue to play a significant role in our future. As the concept matures, the cost of these batteries will drop and they become more widely available. Mckinsey research showed that 1/3 of price reductions can be achieved by using economies-of-scale alone. However, lithium-ion batteries will need to fight for their advantage.
